      Looks like it works. I see a bunch of Super I/O accesses, then COM1, Some port 90h pokes but nobody's listening (POST codes?), PS/2 KBC, and more pokes to 90h and 99h.pic.twitter.com/MEA8cTpxV9

      What fpga board? What are the yellow wires out the side? And what are you using for your design to trace/sniff this?

      bushing's twlfpga (really just a Spartan3E + FT2232H), which I keep reusing for everything. The yellow wires don't go anywhere, but would've been a DSi RAM tracing port, later PS3 flasher. Design is a trivial 8bit logic analyzer in verilog (just dumps raw samples out the FTDI).pic.twitter.com/3zkpp2VEmV

          Yeah... Can understand why you'd keep using it too. Thanks for explaining.
